The new R200 series should have similar connector. My 6970 has a 4pin and a 3pin plugs. I thought yours would be similar. The PSU model number should be printed on the side, so other than the case side panel, you don't have to unplug anything just to see it.
Thank you, I'll check tomorrow morning and post again :) --- PSN: Solidshooter24 Youtube Channel: https://www.youtube.com/user/epicarcadegaming Crash bandicoot 2 let's play! I also play SF4 and MK Online! Check it out!
